Patented June 18, 1907.

To 1/ZZ whom t may concern.-

Be it known that I, JOHN L. MCMILLAN, a

cuse, in the county of Onondaga an( State of New York, haveinvented certain new and. useful Im rovements in Loose-Leaf Binders, of which t e following 'is a specification.

' This invention pertains to loose-leaf binders, and consists in a novel constructionl whereby the user is enabled to hold the binder in one hand and manipulate the' imllalliig removing, replacing or rearranging. the leaves as desired, Without the necessityof laying the binder upon atable or is com-- "The constructionl'isilliistrated in the-ac-A'.

`EFigure. l is a perspective view of the im` proved binder, portions of the lids or eover.- l

As heretofore v'commonly constructed,

bo'thhands to o en and close the impaling hooks orrings, tile binder being laid. 'upon a tableor support to permit the tWo hands to be so used. It frequently hap ens, hovvf ginder, has

or like support. The 'present ,invention meets this Want, affording a ready means of opening and closifngthe impaling hooks or rings by one hand, and leaving the other free :zio support. the binder-, Wliile is being for the *0f the Mansions- Of the-bodes a-bentx anke-daim-ting rod C, we@ erre a' 4 Which the ooks orringmembers these overlapping'ends are as est illustra lclock, by means of connect proximate inner ends oi' the ring sections or members; a lconcave backing orstifening member D, Which serves also as a stop to limit the opening of the hooks or rings; a cover-plate H to conceal themechanism: and the usual back and coverboards E, F, and y The 'ring-support A has its 'longitudinal edges curledover or fashioned into tiifbiilar barrels a, a, to receive and hold pivotgwirei or rods b, b, ori-which are str-img orlpiyoted the .half rings or members c, d of the impali hooks or rings B., The sii rt is :madeo `sheet metal oi' other suitaltilxe0 barrels 11,11/ are cut away at thosej oints at .Sai/'B are located, said membersl beingwheldfyby Athe -Walls of these openings from'shifting'later- Similarly, the cover-plate ,or H' is' notched, coincidenti-'y with the barrels o, and for a like purpose, the Acover being o f slightly arching crosssection, With-inturned edges to fit overand clasp the barrels o,- q, a s shown in ,Figi 2 H Dd 3. ff"

The backing or stiening member is secured to thefback E in any convenient Way,

the ring-support A bein lirst attached to 'said backing, preferably y eyelets or rivets L, thou h other means of attachment ma be adopte if desired. Before assembling t ese parts', the actuatinrod C isapplied to the impaling hooks or ivided rings B, 'the inner ends of whichA are out aWayone-half their thickness so as to'lap each other while the two Lmembers lie in the same plane, and

elongated notche's'dto receiyie rod C. rod is merely a wire of suit- T he ctiiatil` able silliness, avin'g cranked portions e,.

between the divided rins'or pairs of impaling h oks, an`other cran ed portion f, and a `latera ly-'bent end portion g, preferably rovided with a knob o r handle, by Whicli) to rock or oscillatethe rod. The cranked or-V tions eand f are at an angleto each ot er, that-is to say', the portions e extend radially from the main'body ofthe rod at one angle, andthe portion'f at a diierentangle, so that While the portions e'nd 'a' bearing against @Mien .a

provided With TOO ' the' under-facetof the capor coverplate H, 'thplprtion f bears against't'he ring-support nds of a" those portions of the rod which are seated orv journaled in the notches al of the rings or 1m alin hooks actin as 'ivots or journals P g e P for the rod, the cranked portion f will be caused to swing upward and to the left with' reference to the veritcal plane of the axis of the journal portions of said rod, as seen in Fig.'3,that is to say, it will swing to a point pro ressively, farther to the left 'of said plane as i rises toward and a proaches a horizontal position, until' it fina ly clears or ceases. to

hear upon the bottom of sup ort A., as indicated in Fig. 2. The cranke portions e will at the same time and by reason of said rotation of the rod about its journal portions seated in the notches d', swing upward and toward the right.

Owing to the length of the crank portionse and the comparatively ilat arch of cover-4 plate H, said crank. portions e will cause the` pivots or journals -retin 'in the notches d to descend, and to carry` own with them` the inner orshortarrns of the impaling hooks or' ring members, thereby throwing together'the upper or outer' ends of said hooks ormembers an closingthem. The rotation of the rnd C is montinued 'until the crank-arms'fe ass `cover late H, against which they bear with ,'gesome ore'e by reason'of the natural outward slightly beyond the'middle .of the arch o the pressure bf the leaves. tending t0 4'open the rin s and to lift the pivots and the rod C.

in' position by the coverplate Hand 49- o prevent the crank-arms e from. assing materially beyond such middle or ocking point, a stop fi is rovided, which ,maycon-V -veniently be astrip or block of wood fitted; within the supporting member A,'notched to receive one of its linturned edges, 'and .retained two rings, between which it lies, Vas seenini-Fig 1 The stopblock is shown detached in Fig. 5, and-in position in Fig. '3. `j When the rodC fs rotated'in the reverse direction or backward with reference to the travel of the hands of a clock, the cranked portion f bear' upon the su port A causesV the journal poiitions of the ro or those por' ti'ons seated in the. notches of the ring meinbers to rise, thus rocking the e ring members c, d, upon their pivot rods b and causing said membersto separate and the rings ,to open,

tageous to carry a sheet of flexible material 1,-;79., woven fabric, leather', or'the like,-

over vthebackin 4member D and ac rossthe inner. faces of t e -co verboards F and G,

'cementinfor otherwise securing it tov the j folding it back under the raised latter-,lah edges ufthebaclnng, as seen in Figs. l 2 and .31. however, isoptional, butadds both' to the finish and-the strength ofj the structure. ltfwill,be' seen that by -thisfconstruction' the impfling; hooks ordivided rincg s are given a firm supppr't b othfwhen openean'd' when sibling the para 1 and it ativan;

fand ivotally mounted in said va ro,

closed, and the manipulation of the rings and of the leaves by pue hand is rendered possible and easy. y This is a great desideratum in binders of this class.

Having thus described my nvei'iti'on, what I claim is: i

1.' In a binder, the combination of a troughlike support; a series of divided `rings pivotally supported therein; a cover;

and a rod having pivotal or journal portions seated in the inner ends oi the divided-ring sections, and cranked portions adapted to bear respectively against thel trough-like supportA and against Vthe cover and to lower the pivotal or journal-portions when said rod isrock'ed'or turned.

2. In `combination with a backend coverboards E, F, G, a concave vstiifening member a trouglilike ringsupp'ortiug member A; `divided rings B, having their members sepa- .rately pivoted to opposite edges oi said'supportingv member; cover H; and actuating rod," pivotally supported in the overlapping innen endsg'o'flthc ring members, provided with cranked portions aj', and operating handle g, and serving, when turned, to raise or lower the proximate inner ends of the divided rings.

3. In'a' binder, the combination of a back and cover-boards; 'a trough-like holder or support; a cover therefor; two-part rings,

the members oi whichv are :sep arately' and plv otally'inounted inv said support; and a locking rodhaving journal portions mounted in theproxiinate inneriends of the divided-ruig 'members Vv'and having cranked portions to and its cover.A

` 4. In abindcr, the combination with a support and' divided rings having` their membersseparately and pivotally mounted in bear respectively against the ring-support said support, and having ,their proximate in- -upo n s aid. support and its cover; .and a stop jto limit the movement ofthecranked portions ofthe rod.

6. In a binder., the combination with a trough-like sup ort and its cover, of two-part rings 'the mem ers 'of which are separately support; and or'rock-,shaft journals inithe overlapping inner ends of said ring members, and having a cranked portion which, 'as the rod is ICO IIO
